Abstract
A helix antenna includes a base portion for containing a feed network including a power input, a 90 degree power splitter in communication with the power inlet, and first and second 180 degree power splitters in communication with the 90 degree power splitter. A support tube is mounted on the base portion, and a plurality of disk separators are mounted on the tube. Four elongated elements are wound around the tube and are spaced therefrom by the disk separators. The elements are connected to end-most lower and upper ones of the disk separators, the elements extending toward a center feed point of the upper disk separator. First and second radially opposite pairs of feed cables are wound around the support tube, extending from the lower disk separator to the upper disk separator, and are in communication, respectively, with the first and second 180 degree power splitters.
